IPC-4413 standard covers finished fabrics woven from low Dk electrical grade glass fiber yarns that are intended as a reinforcing material in laminated plastics for electrical and electronic use. All fabrics covered by IPC-4413 standard are plain weave.

Tackling PCB cleanliness is a tough job; residues on printed circuit boards are directly related to the reliability of the produced hardware and can result in serious failures if not known or monitored. But how do you measure "cleanliness"? How clean is "clean"? The IPC-5701 provides guidance into how these issues should be approached and specified in purchasing documents, addressing levels of...
